Since 1985 in the region of Wuerttemberg Germany mating disruption against Eupoecilia ambiguella is used. Since 1993 it is also used against Lobesia botrana. The use of mating disruption is continuously increasing so that up to now 75 of the vineyards are treated with pheromones. In the first generation the effect of mating disruption was lower than in the second generation, however sufficient. Sometimes problems occurred at the borderline of the treated area due to an immigration of mature females. Very rarely the disease incidence of the second generation exceeded the damage threshold of 5 attack. The overall rate of successful pheromone treatments was better than in vineyards treated with insecticides. The use of pheromones in viticulture seems to be more a social problem than a technical problem .
